Enjoy the RZ Not that I have one I do have a RB67 Pro S.. RZ lenses are pretty costy compared to the RB ones. KL lenses are the exception tho those things are at a premium price too. My RB with 50mm 90mm and KL140mm. Prism finder and LH trigger grip stand me signigifigantly less money than an RZ with just one lens. Plus I much prefer full mechanical. Electronics and batteries can suck. Try getting an RZ fixed. I also own a Bronica SQ. Electronics on that have reared thier ugly head,.replacement component, the only feasible answer.
